There are many types of distributors, and the most commonly used is the Perforated pipe distributor with holes in pipes.

To inject 3.6 m3/h of water (1000 kg/m3 of density and 1 cP of viscosity) into the device, design a distributor with 10 holes of the same diameter evenly spaced into a pipe with an inner diameter of 25 mm long of 0.7 m. In other words, calculate the diameter of the hole and the pressure loss at this time.
